The vacuum sintering furnace is suitable for operating temperature of 1000 deg C. The hot zone chamber size of the furnace is 200 mm x 200 mm x 200 mm ( H x W x D). TiO2 Granules of Size 6-10 mm is sintered inside the furnace at 1000 Deg C with vacuum of 10-4 mbar. The vacuum chamber shell is made of Stainless Steel (SS304) material of cylindrical shape with thickness of 6 mm. The SS chamber is front loading type with water jacketed flange for cooling. The pumping system consists of diffusion pump, rotary vane pump, nitrogen trap etc. The working vacuum inside the chamber is 2 X 10-4 mbar at temperature of 1000 Deg C in empty & dry condition within 6 hours.

The High Temperature vacuum furnace is used for sintering of the silicon nitride material. The sintering of Silicon Nitride ceramics will be done in Nitrogen Atmosphere at high temperature. The maximum temperature of the furnace is 1700 deg C. The furnace consists of inner vacuum chamber. The chamber has high temperature ceramic fiber boards insulation. MoSi2 heaters are used to achieve the desired temperature. The system also has vacuum system to achieve the vacuum of 10-3 mbar inside the chamber. The vacuum system will consist of Mechanical rotary pump and backing roots pump of leybold make. There is also two stage gas manifold system to purge the nitrogen gas inside the furnace during the sintering process. The furnace will be vacuum in dry cold conditions

Furnace Calibration For Furnace Calibration two type of test are there System Accuracy Test (SAT) Temperature Uniformity Survey (TUS) 1. System Accuracy Test: System Accuracy Test, commonly referred to as an SAT, is another critically important and often required test. System Accuracy Tests are performed to determine the error within the temperature control system (temperature control device/lead wire/thermocouple). Regardless of the application, knowing the error that exists in your temperature control system allows for more consistent control of quality 2. Temperature Uniformity Survey: Temperature Uniformity Survey (TUS) is a vital part of the overall equipment performance and validation that ensures the heat treat/vacuum furnace repeatedly

Stove Dome & Brief process of Stove Dome Stove is an important part of the iron making in Blast Furnace process and the temperature inside is above 1050°C. The stove is first heated up by burninggas and combustion air within the chamber and allowing the heat to be absorbed into the refractory brick. When sufficient heat has been absorbed, the stove is put on-blast. In this mode, no combustion takes place, but cold blast air is forced through the stove and absorbs the heat to become hot blast. This is then mixed with cold blast to bring it to the right temperature, and is then forced into the blast furnace via the tuyeres which is the other section of this process. It is quite common to have three stoves, so that at any time one stove is on-blast while the others are on-gas or boxed. A boxed stove has been heated up to temperature and sealed, so that it is ready to go on-blast. If one stove is down for repair, it is possible to run on just two stoves

Blackbody is an idealized body that absorbs all incident electromagnetic radiation, The name "black body" is given because it absorbs radiation in all frequencies, not because it only absorbs, a black body can emitblackbody radiation. In this blog post, we are discussing about the Extended area black body and its significance Before start to describe it let's talk about some basic things about it. As we know that a blackbody is a physical material with zero reflectivity and perfect emission. The main applications for these sources are calibration of Non-Contact Temperature sensors such as thermal imagers, Pyrometers. Types of black body : In the pyrometer calibration industry many types of black body available which are different in size, shape and body structure. Every black body have different dimension and shapes. These are available in the industry in wide range. Extended area blackbody is one of them in this blackbody. Extended area
